Lightroom mobile: Makes selection save when you leave the photo

I’ve edited the same photo 4 times now. If I accidentally leave the photo all my selections disappear and I have to start over. This didn’t use to happen. I’m not editing this photo again till it’s fixed

Can you confirm which operating system please? That's a fairly essential detail. And when you say you leave the photo, you mean you move to another photo in LR, or you move to another app? What kind of selections are disappearing?
